Description:
------------
imagegif() does not product interlaced gif images when interlace bit is on. memset() overwrites actual value of interlace bit in php-5.1.4\ext\gd\libgd\gd_gif_out.c at line 270.

Reproduce code:
---------------
php-5.1.4\ext\gd\libgd\gd_gif_out.c:268

        ctx.Interlace = GInterlace;
	ctx.in_count = 1;
	memset(&ctx, 0, sizeof(ctx));

Expected result:
----------------
	memset(&ctx, 0, sizeof(ctx));
        ctx.Interlace = GInterlace;

(ctx.in_count is later assigned to 1 in function compress() at line 514.)
